My Jack Dempsy has been itching up a storm. I was worried he had ick, but when I looked closely at him, there were little (about .5mm) white (rice looking) things crawling all over his skin. The pet store people said they have never seen anything like this before. I've also been having an issue with cloudiness in the tank. Here is a link to a video, if you look on his head, you can see them.
